ALARM ATTACHMENT FOR BALlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 301,883, dated July l5,1884.

` Application filed May 17, 1884. (No model.) A Y To a/ZZ whom if mayconcern.

. not in use, or for other purposes, this being a Be it known that I,JOHN L. HALL, a citizen of the United States, residing at Colony,

in the county of Anderson and State of Kansas,

have invented certain newA and useful Improvements in Alarm Attachmentsfor Baling- Presses; and I do hereby declare that the following is afull,-clear, and exact description of the same, reference being had tothe an'- neXed drawings, making a part of this speciiication, and to theletters and gures of .reference marked thereon.

Figure 1 of the drawings is a perspective view showing my inventionapplied to a baling-press. Fig. 2 is a perspective view of the alarmattachment on an enlarged scale; and Fig. 3, a cross-section in detail,taken on line y y of Fig. 2. A

The present invention has relationto alarms for baling-presses; and theobject thereof is to provide an alarm device that may be readily appliedto what is known as the perpetual baling-press, and is especiallyadapted thereto for regulating and obtaining a uniformity in the lengthof the bale as it is delivered from the press, giving a warning to theattendant when to drop a follower or bale-head and begin the formationof another bale.

The construction of the alarm device and its application to abaling-press will be hereinafter described, andv subsequently pointedout in the claims.

In Fig. l I have shown the end only of what is termed a perpetualbaling-press77 used for baling hay or other material, and as the pressmay be of that class most used any further description of it isconsidered unnecessary.

The alarm attachment consists of a rectangular frame, A, provided withears a, through which passes a rod, b, having its ends secured to theside beams of the press. This hinging or pivoting of the frame A enablesit to be swung up out of the way when the alarm is decided advantage.The frame A has a central elongated opening, '0, in which is located thefrictional roller B, said opening being `of such length that rollers' ofincreased diameter and circumference can be substituted when desired tohave the bales of greater length, as will be hereinafter more fullydescribed. The

frame A is provided with a standard, C, to the upper extremity of whichis attached a bell,

D. A suitable hammer, E, is connected to the standard C in the'followingmanner, the shank of the hammer extending down near the slot or openingc of the frame: To the standard G is removably connected a screwrod, d,over whichis placed a sleeve, e, and

. over this sleeve is placed the hammer E, the

shank thereofA being formed with an eye or opening sufficiently largefor the purpose. Around the sleeve e, upon both sides of the hammer E,is coiled a spring,'F, it being bent above the sleeve to form a yoke, f,and below the sleeve the free ends of the spring bearing against a pin,g, projecting from the side of the standard. The yoke f of the spring Fbears with considerable force against'the shank of the hammer E, andretains it in an upright position, as shown in Fig. 2. As the roller Brevolves, a pin, h, upon the side thereof will be ybrought in contactwith the shank of the hammer, which will throw orvforce outward theupper end thereof, and as the pin is carried around, the spring F willcause the hamvmer to be brought against the bell D with such forceas tostrike an alarm.

The sleeve @and the peculiar construction of the spring F are bothessential elements in the device, the sleeve being so formed as to turnwith the hammer. screwthreaded rod d, the spring, hammer, and sleeve canall be detached from the standard,

-as may` also the bell D.

l The tripping-pin h is made preferablyremovable, and can be reinsertedin a hole nearer the periphery of the roller, so as to increase thepower of the hammer against the bell when the pin strikes it. A seriesof grooves, i, are provided for this purpose, and also to adapt theframe A to rollers of varying sizes, the grooves also allowing thechange in position 0f the pin.

In order to increase the frictional surface of the roller B and the hayor other material being baled, the peripheryIform with V-shaped ribs 7c,as shown in Fig. 1, so as to prevent the danger of the slipping of theroller when the hay is passing through the press. As the roller hascompleted one revolution, the pin in the side of said roller will causethe bell to By removing the IOO be sounded, as hereinbcfore described,thus giving notice to the man feeding the press to drop a follower orbale-head in the press and begin the formation of another bale.

Any desired length of bale can be obtained by taking out one roller andsubstituting auother of different diameter, thereby overcomingcompletely the Want of uniformity in the length of the bales, caused bythe negligence of the attendant in not Watching when the bale is made.The alarm attachment relieves entirely the attention of the feeder orattendant to the forming of the bale, thereby enabling him to do moreWork in a given time, and have all the bales uniform in length, andconsequently very nearly so in weight. rIhe frame, with the alarm, canbe readily detached from the press and removed by withdrawing the rodthat is connected to the beams, and can be as conveniently replacedWithout any annoyance or trouble in the use of tools.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. The combination, with a perpetual baling-press, of an alarmattachment consistingv of a slotted frame hinged or pivoted thereto andremovable therefrom, said frame having a roller revolving in the slot,and carrying a pin which operates an alarm composed of a hammer and bellconnected to a standard on the frame, substantially as and for thepurpose set forth.

2. rIhe combination, with a perpetual baling-press, of an alarmattachment consisting o'f a slotted fra'me containing a removable rollercarrying a pin secured to its side, a standard projecting from thevframe provided with a bell and hammer, the latter being connectedthereto by a screw-rod, sleeve, and a spring coiled around the sleeveand bent to form a yoke to press against the shank of the hammer andforce it against the bell when released by the pin in the side of theroller, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JOHN L. HALL.
